In this engineering challenge, you will use limited materials to build a paper tower as tall as possible, but there's a twist! Your tower must also support a heavy weight at the top without collapsing. Looking for inspiration? You can see how other students have tackled this and other annual Science Buddies Engineering Challenges.
Teachers, lesson plan versions of this challenge are also available.

Landslides are powerful geological events that happen suddenly, causing fear in people who live in areas with unstable hills, slopes, and cliff sides. Landslides damage the surrounding habitat and can destroy homes in their path. But what causes landslides? Can slides happen on any slope, or do slopes have to have certain characteristics, such as a steep angle and a specific material mass? In this geology science project, you will learn about the different types of landslides and the…

You probably know that turning off the lights and the water, and not wasting paper are all ways to help the environment and conserve our resources. Did you know that another way is to use fuel cells? A fuel cell is a device that converts the energy in chemicals to electricity and it creates no pollution. The starting chemical does not have to be something complex — in fact you it can even be water! In this science fair project try your own hand at converting water to electricity with the…

Have you ever ridden on a carousel, or a merry-go-round, at an amusement park? On a carousel, you usually get to take a seat on a wooden horse or other animal that spins around and around as the carousel is turned on and powered by electricity. Another smaller type of carousel that people can have in their homes is a candle carousel, which is powered by heat from candles. In this science project, you will get to make your own candle carousel and investigate how the spinning speed of the…

Bridges are big and beautiful structures, but they also need to be safe for the people who cross over them every day. Building a bridge that is safe and secure is a challenge to civil engineers. But the job is even more challenging if you live in earthquake country! Find out how engineers are solving this problem as they build a new bridge over the San Francisco Bay in California. Try some of your own Bay Bridge designs. Will your bridge design take the shake of a quake?

Have you ever seen a geodesic dome? Geodesic domes are approximately sphere-like (or partially sphere-like) structures made up of interconnected triangles. A famous geodesic dome is Spaceship Earth at EPCOT in Walt Disney World, Florida, but geodesic domes are also commonly found as climbing domes at playgrounds. In this science project, you will get to build a geodesic dome using rolled-up newspapers and tape. How much mass do you think your dome will be able to support? Build one and find out!

When your parents were kids, they probably wore polyester. Static cling was a major household issue! Now everybody wears cotton, which does not get static cling nearly as much. Why are some materials more susceptible to static cling than others? Investigate how well different materials produce static electricity by making a homemade electroscope and testing it out in this science project.

How do you feel when you ride your bike into a strong wind? Do your legs feel like lead? How about when the wind is at your back? Does that make you feel ready for the Tour de France? In this science fair project, you will investigate how wind-powered devices, like pinwheels, also react in different ways to the direction of the wind.
